Can you trust your senses?=
1. Where does the most bending of the light occur in the eye?
Cornea when light is reflected into the eye the cornea is the part that bends and can get bigger and smaller acording to how much light must be taken in.
2. Describe how the lens works?
The lens bends the light to strike the retina correctly. This is called refraction.
3. Why do we squint when exposed to bright light?
===Because your eyes haven't adjusted to bright sunlight. Your pupils control the amount of light let in by your eyes. Your pupils haven't closed enough and there is too much light getting in, so you make it less open by squinting your eyes and cutting off the excess light until your eyes adjust.

4. Which parts of the eye are involved in focusing?
the lens and the cornea are the main parts involved in focusing. The Ciliary Muscles open up large to let the lens see and show light to your retina.
